INDIAN DRAGONFLIES, 117 
Abdomen. Segment 1 is reddish buff, segment 2 is only blue for quite a small 
area on the dorsum, its sides being silvery white. The ground colour is brown 
rather than black and the spots are larger, less defined and paler in colour and 
often coalesce. 
Anal appendages lanceolate, with a stout mid-rib, brown. 
Dentigerous plate rounded and coated with small denticules. 
Hab.—Throughout India in the planes and submontane areas except in the 
dry zones. I have taken specimens in Madras, Ceylon, Bombay and Poona 
but have not seen it in the C. P. or Bangalore. It is most abundant in the 
area of country lying between the ghats and the sea on the Western side of India 
south of Mount Abu. Dr. Annandale has sent me specimens from Barkuda, 
Ganjam District, where he states that it is common. It may be seen hawking 
throughout the day along the borders of the Chilka Lake. I have seen the 
female ovipositing in quite small tanks in Poona and Bombay and have bred 
out larve obtained from a tank not more than 20 feet across. Clean, weedy 
tanks are the favourite spots to find them. The imago in Poona always 
emerged punctually at about 10-30 p.m., and the full colours had almost 
developed by dawn. 
The species described by Dr. Laidlaw as Series C, from Assam and Bengal 
although closely allied to A. guttatus are I believe A. bacchus and are described as 
such below, hence I define the limits of true guttatus for the present as south 
of the montane areas of the Himalayas. Eastwards it extends into Burma and 
throughout the Straits and Indo-China.

Male.—Length of abdomen 50 mm., hindwing 48 mm. 
Head : eyes in the living state bluish grey ; face pale green; labrum and 
labium yellow, the former more or less bordered with black; vesicle yellow ; 
frons pale green in front, yellowish green above and marked with a broad, black. 
T-shaped mark ; occiput black (In specimens from Shillong and the Himalayas, 
the occiput is straight behind thus differing from Anazx quttatus in which there 
is a minute point at the centre. In these specimens also, the colour is brow- 
nish black). (In a specimen which I have examined in the British Museum and 
which is labelled A. bacchus, the occiput is greenish yellow, the centre is raised 
into a pyriform bosse and the free border is laminated, cleft in the middle by 
a shallow notch, thus forming two laminated scallops. I think however that 
this specimen is a local race of A. parthenope julius.) 
Prothorax brown, hidden almost entirely by the overhanging head. The 
thorax matt green, unmarked save for some occasional bluish spots on the 
tergum and the sutural lines which are obscurely blackish brown. 
Legs black, the anterior femora yellowish at their bases. 
. Wings hyaline, the costa yellow outwardly, enfumed at the apices and diffuse- 
M4 along the termen as far as the 6th nervure (M3) ; membrane blackish brown 
r greyish black, its base not pale as in guttatus; stigma dark ochreous with 
wean ; 9°16. | 16:39 10217 [19-10

trigones 4 to 6 cells, 4 to 5 cubital nervures ; hypertrigones traversed 2 to 3 
times. 
Abdomen. Segment 1 matt green or pale brown, segment 2 sky-blue above 
and on the upper part of sides, the dorsum marked with a mid-dorsal line 
of black, connected with two transverse lines of the same colour,
